Dangerous Metal Buckles
I love my two Domke bags, the F-3X which I carry everywhere and the F2 which I use mainly for portable lighting stuff.
But I sure wish my camera bag didn't have those huge metal buckles. They've whacked my camera several times, and I feel really lucky they haven't yet hit the glass of one of my lenses, or cracked a camera LCD.
I've been meaning to have a local shop remove the buckles and swap in plastic Fastex buckles, but I haven't yet found anyone who'll do it.
So there's my suggestion -- plastic buckles, at least on those big, swinging straps, please.
